Abstract

A multi-band antenna includes a base plate, a first radiating element, a second radiating element and a third radiating element. The base plate has a first edge, a second edge opposite to the first edge, a third edge and a fourth edge both connecting the first and second edges and opposite to each other. A feeding portion and a ground portion are both extended from the first edge and respectively adjacent to the third edge and the fourth edge, and an opening is formed between the feeding portion and the ground portion. The first radiating element extends from a portion of the second edge adjacent to the third edge and spatially fences the second edge and the fourth edge. The second and third radiating elements tortuously extend from the third edge and are arranged adjacent to each other.
